DONALD E. GREEN ATTORNEY May 6, 1952 D. F. GREEN 2 PIPE FOR SMOKING TOBACCO AND BAFFLE UNIT Filed May 12, 1947 2' SHEETS-SHEET 2 INVENTOR. DONALD F. GREEN Patented May 6, 1952 UNITED STATES PATENT OFFICE PIPE FOB SMOKING TOBACCO AND BAFFLE UNIT Claims. 1

My invention relates to a pipe for smoking tobacco, in which I provide a series of bafiles in the stem which tend to cool the smoke and cause the condensation therefrom to be absorbed by a wick and filter extending along the baffle unit to the bit of the pipe.

A feature resides in providing a baffle filter unit in the stem which may be readily removed with the bit of the pipe or which may be supported in the shank of the bowl and then removed therefrom for cleansing and replacement of the filter and wick member.

A further feature resides in providing the baffle unit with a series of upstanding baflies which extend along through the stem of the pipe, and providing each baflle with an opening through which the smoke may pass, the openings of the adjacent baffles being staggered to carry the smoke in a tortuous manner through the baflle unit. The balfies of the unit provide walls which contact the inner surface of the stem to shut off the passage of smoke around the baflies and causing the smoke to pass through the staggered openings in a tortuous path through the stem and out through the bit.

A further feature resides in providing the wick or filter as a removable insert and the passageway through the baflie unit for the wick may extend in a path elevated from the lower surface of the baffle unit or the opening for the wick may extend from the compartment formed by the bafliles to the lower edge of the unit. The removable wick and filter may be made of any suitable material and may be in the form of a folded pipe cleaner or any other fibrous material which is adapted to have an afiinity or highly absorbent nature to collect the condensation from the smoke and thus provide a dry, comparatively cool and de-nicotized smoke coming from the bit.

It is a primary feature to provide a baffle unit which may be readily removed from the hollow stem of the pipe, and which gives free access to the filter and absorbent wick, so that the pipe may be kept in a clean, sanitary manner.

With the use of my pipe the smoker draws smoke from the bowl and the smoke must follow a tortuous path, the path being of considerable length in a given stem length, thus providing a cooler smoke by reason of the lengthening of the path which the smoke must follow from the bowl to the bit. Another feature of my invention resides in providing a bafile unitwhich due to the passage of the smoke through the bafiles, prevents passage of slugs of the tobacco therethrough.

These features, together with other details and objects in the invention will be more clearly and fully hereinafter set forth.

Fig. 7 is across-section on the line I--I of Fig. 5. s

Fig. 8 is a cross-section similar to Fig. 7, but of a modification, showing the wick well extending to a lower point than it is shown in Fig. 7.

Fig. 9 is a perspective view of the bit and bafile unit wherein the bit and baffle unit are formed integral, as shown in Figs. 4 and 5, and the unit is removed from the casing comprising the stem.

The pipe A is provided with the usual bowl B for the tobacco and a shank I0 extends from the bowl to which the stem II is adapted to be attached by frictional engagement with the reduced shank portion I2. The bit portion l3 may be formed integral with the stem II, as illustrated in Figs. 1 and 2.

Within the shank I0 and the stem II I provide a baiiie unit C. The unit C is made up of a series of baffles I4 which are formed integral with the base portion I5. The base portion I5 is adapted to extend the length of the unit C from the shoulder I6 within the shank ID to the shoulder II formed in the stem I I.

The unit C may be formed with a suitable number of baflies I4 which are spaced apart to form a series of smoke compartments I8 between the bailles. Each baffle I4 is provided with a small smoke opening I9, and the opening I9 of one .bafiie is staggered in relation to the opening of the next adjacent bafile. This provides a smoke passageway from the bowl B of the pipe to the bit I3. The bit I3 is provided with a smoke passageway 20 which connects with the chamber 2| in the stem I I in which the baffle unit C is located.

Extending throughout the length of the unit C I provide a channel 22 in which the absorbent wick and filter member 23 is located. The channel 22 extends into the compartments 1% of the unit C. When the absorbent wick and filter member 23 is in place in the channel 22 a portion of the wick will be exposed in the smoke compartments [8. This is important because it brings the smoke passing through the compartments 18 into direct contact with the absorbent filter. Thus the wickfilter 23 will collect any moisture from the smoke as it passes from the bowl B through the unit C and to the passageway 2% in the bit it. Some of the smoke may be drawn through the filter 23. However, most of the smoke is drawn over the filter and from one compartment l8 to the other, being delayed by the baflle members M as the smoke is caused to follow a tortuous path through the unit C.

In the construction illustrated in Figs. 1 and 2, when the stem II is removed from the shoulder [2 the unit C remains connected to the shank l and projects therefrom, owing to the fact that the shank i0 is formed with an opening 24 which is adapted to frictionally hold the inner end of the unit C in the shank until it is removed for cleaning and the replacing of the absorbent wick and filter member 23.

My pipe may be made in the form illustrated in Figs. 4 and where the bowl B is connected by the shank H) to the straight cylindrical stem 25, which houses the baflie unit C". The cylindrical stem portion 25 may be made of any suitable material and may be transparent to disclose the unit C therein, if desired.

In this construction the baflie unit C is formed integral with the bit 25. The unit C is formed with a series of baffle walls 21 which are similar to the baffle walls l4 and which are provided with small, staggered smoke holes 28.

When the bafiie unit C is in place in the cylindrical stem 25, the baffle walls 2'! seal the smoke compartments 29 from each other and thus the smoke is caused to pass through the openings 28. These openings 28 are small enough to prevent particles of tobacco from being drawn through the baiile unit C.

The bit 26 is formed with a smoke opening 39 extending therethrough which connects with the smoke compartments 29 by means of the openings 28.

The bowl B connects with the smoke compartments 29 by means of the passageway 3| extending from the bowl to the chamber in the stem wherein the unit C is maintained.

The unit C is formed with a longitudinal channel 32 which receives the absorbent wick and filter member 33. The wick-filter 33 is similar to the. wick and filter member 23 and these absorbent wick-filters may be made of any suitable material and in fact may constitute an ordinary pipe cleaner folded and extending within the channels 22 and 32. The absorbent wick and filter 33, extends, in a manner to be exposed in eachof the smoke compartments 29. Thus as the smoke passes from the bowl B to the bit 26 it will be caused to contact the wick and filter 33 which acts to absorb and collect any moisture, nicotine, or other substances condensed from the smoke as it passes through the unit C or the unit C.

I provide an alternative bafile unit C illustrated in cross-section in Fig. 8, through which extends the passageway 34, the passageway 34 opening into the smoke compartments 29 and also bein exposed to the inner surface of the sleeve whichv forms the stem 25 at the point 35. Thus in this form the longitudinal passage 34 extending through the unit C is open along the bottom surface of the unit C". This permits the wick and filter member 33 to be inserted through the opening at the bottom of the unit C and also permits it to be readily removed from the unit.

In the form of the baffle unit C and C the same is formed integral with the bit 26. Thus when the bit 26 is removed from the stem portion 25 the bafile unit C or C is removed with the bit and the same can be readil cleansed as well as replacing the absorbent wick and filter 33. In Fig. 9 I have illustrated the unit C with the bit 26 removed from the cylindrical stem 25.

My pipe provides a means of condensing any moisture in the smoke as it passes through the unit C, C, or C and at the same time collecting any moisture or condensation from the smoke into the absorbent wick and filter 23 or 33, thus providing a dry, clean smoke out of the bit of the pipe. The tortuous path which the smoke must follow delays it long enough in the baflie unit to cool the same and prevent burning of the tongue by the smoke coming from the bowl B of the pipe.

Furthermore, in my pipe the smoke primarily passes over the absorbent wick and filter rather than through the same and thus the smoke is not unduly retarded but is clarified by reason of the fact that the absorbent wick and filter member readily collects any moisture, nicotine or other substances from the smoke and prevents these objectionable elements from being drawn out of the bit of the pipe in smoking.
